SHIAWASSEE COUNTY, MI -- For the second time in about two weeks, the county has declared a state of emergency.

It will remain in effect until the roadways are clear, according to Shiawassee County Emergency Management.

"Shiawassee
County is currently under a state of emergency due to heavy snow fall
amounts, blowing and drifting snow causing roadways to become hazardous
and impassible," it says on its Facebook page. "To avoid accidents and to aid public safety response, all residents are urged to stay off of the roads at this time."

A state of emergency also was called just before Christmas after a massive ice storm knocked out power to thousands.

All schools in the county are closed.

"Road
Commission crews will continue to plow the primary roads throughout the
night, this Local State of Emergency will expire once confirmation has
been received that roads are clear and passable for public safety
response and residential travel," the Facebook post says.
